3 Proper use

The axial fans of the series AXC/AXR/AXCBF in the versions B, D, G, P, (K), (B) are intended for installation in ventilation systems!

The axial fans of the series AXC/AXR/AXCBF in the versions B, D, G and P are ready-to-use products and are used as components for ventilation appliances, machines and systems. With these fans, air can be sucked out, inserted or also conveyed. As a standard, the fans are supplied with a thermal motor protection (PTC).

The fans can be installed both in channel systems and also with free suction via an admission nozzle and a suction-side contact protection grid. Free blow-out via a contact protection grid is also possible following prior consideration during design.

The axial fans may not be used in areas in which an explosion-capable atmosphere can be found. The fans are not suited for suction of dusty or aggressive media or media with such a content of dust that operation of the fan could be impaired by accumulation on the blades and on the fan housing.

• The maximum admissible operating data on the name plate apply to an air density ρ =1.2 kg/m³ (See level)and a maximum air humidity of 80 %. The fans are suited for an ambient temperature of no more than 55 °C (pay attention to information on name plate). The temperature of the material conveyed may not exceed 55 °C or fall below –20 °C.

• The maximum admissible temperatures stated above can be increased to an ambient temperature of 60 °C, 80 °C or even up to 100 °C (pay attention to precise information on name plate) by use of ISO H motors. The temperature of the material conveyed may then not exceed 100 °C or fall below –20 °C.

• With the use of specific motors (pay attention to precise information on name plate), the fans can also be used up to a maximum air humidity of 95 %.

• The motors cannot be voltage-controlled. Speed regulation is only possible via a customary frequency inverter, e.g. Systemair FRQ or FXDM.

Special points in the assembly of the types of fan:

Notes on the installation of the air channels

NOTE Risk of damage to the fan. If the dampers are fitted incorrectly, they will not function. Install the air-acting dampers vertically. If you install the air-acting damper horizontally then only with the damper opening pointing upwards. NOTE Risk of damage to the fan. If the flap traps are fitted incorrectly in smoke exhaust fans, no warranty will be assumed by Systemair! Only install the flap traps in smoke exhaust fans in the air direction behind the fan (pressure side). This is the only way to comply with the tested arrangement. NOTE Risk of damage to the fan and the complete system! If unsuited fittings are used, the smoke exhaust fans can become loose. Only use fittings with fire resistance classes which match the case of use in question! NOTE Risk of damage to the fan and the complete system! If unsuited materials are used for channel systems of smoke exhaust fans, damage can occur on the fans or on the overall system. Only use fittings with fire resistance classes which match the case of use in question! NOTE Risk of damage to the fan and the complete system! If there is not sufficient access to the fitted fan, maintenance work cannot be done to the necessary extent. In the case of damage, remedying the cause may be hampered. In both cases, subsequent damage to the fan and to the overall system is possible! Fit the fans in such a way that there is sufficient access for maintenance and upkeep purposes!

Type Special points in the assembly:

AXC-D

In the „D“ series, the axial roof fan is to be fitted on a correspondingly stable base. You will see the weight of the fan in the corresponding table. In order to avoid formation of condensation, the base is to be insulated from the inside. The base is to be integrated into the roof tightly by the customer, e.g. by adhesion with welded tracks of bitumen on the base.

AXC-P

The „P“ series of axial fans is to be fitted to a wall construction. The wall construction and the fitting of the fan must be adapted to the weight of the fan. You will see the weight of the fan in the table under Point 10.1 Transport.

AXC (B), (K), (F)AXR (B), (K), (F)

Smoke exhaust fans are suited for positioning inside a building in the fire room, inside the building in a separate room and out in the open. If they are positioned outside the fire zone, but still inside the building, the fan must be provided with heat insulation by the customer. The heat insulation must be provided with fireproof material L120 according to DIN 4102-4.

45AX - 01.2013


To ensure achievement of the characteristic, it is necessary for an even and irrotational flow to be available at the inlet.This is achieved in free intake by the addition of an admission nozzle or a stretch of channel with a length of no less than 2.5 x D. If this is not possible for construction reasons, a deflector with baffle sheets arranged in front of the fan must be optimised in its flow engineering properties in such a way that an even distribution of speed is achieved at the fan inlet. On the pressure side, a channel or tube with a length of no less than 2.5 x D is to be provided in order to achieve the characteristic. Contact with rotating parts must be ruled out at all times – either by channels of a corresponding length or by protective grids.

The fans have suitable sealing measures. However, the manufacturer assumes no warranty for connections by the customer. When the fans are fitted, the operator of the system must carry out a leakage test of the system (before commissioning!) in accordance with legal requirements.

The complete channel system via which smoke and fire gases are exhausted must fulfil the required fire resis-tance classes according to local regulations.

When fitting the flexible connections, make sure that they are fitted according to the stretched length (see following table), without congestion or tensile strain. They are not used to compensate any lack of precision in the assembly.

Install the flexible connections offset, so that there is no reduction in efficiency or a development of noise.

10.4 Electrical connection

DANGER! Risk of injuries from electric current! Switch the energy supply off before you bring about the electrical connection of the fan. Make sure that the energy supply cannot be switched on again prematurely. The electrical connection may only be carried out by trained electricians. DANGER! Risk of injuries from electric voltage! Check whether the electrical data on the name plate match up with the local mains connection, e.g. of the switch cabinet.

The electrical connection is to be done according to valid directives and only by a qualified fitter with matching safety devices for the protection of the motor (start and overload).

The nominal data on the name plate of the device must match up with the mains voltage and frequency.

Voltage tolerances are admissible with a maximum of +6 % or –10 % according to IEC38. The measured current may only exceed the nominal current at nominal voltage by a maximum of 5 %.

Fans provided with resistors (PTC) must always be connected to an external motor protection. The motors cannot be voltage controlled. Speed regulation is only possible via a customary frequency inverter. The wiring scheme and the manufacturer‘s declaration from the manufacturer of the motor have been enc-losed with the documentation.

• Carry out the electrical connection directly on the connection box according to the wiring scheme in the lid of the connection box and comply with local directives.

Special points in the assembly of the types of fan:

• Please find the electrical data on the name plate or the enclosed data sheet.

It is recommended that all motors are to be provided with a protective motor switch (not included in the scope of delivery). Nothing may be fitted to the fan housing.

10.5 Adjusting the blade angleIf the operating point of the fan has to be changed and adjustment of the blade angle is necessary, please get in touch with the Systemair service department at all costs! Adjustment of the blade angle requires know-ledge of the current consumption of the motor and the maximum admissible blade angle relative to the motor installed.

11 Commissioning

DANGER! Risk of injury and risk of damage to the fan. Before commissioning, read the operating instructions carefully and check the following: • positioning of the device (fitting, possible deformations) • assembly residue and foreign bodies removed from fan area and connected channel • safety devices fitted • leakage test carried out • correct performance and correct connection to the electrical installation • correspondence of the connection data with the information on the name plate • Before commissioning, check the minimum air gap between the tip of the blade and the housing once more (see Point 10.3 Assembly).

DANGER! Risk of injuries to the eyes by residue or dust being swirled out when checking the direction of rotation. When checking the direction of rotation of the rotor, wear protective goggles! • If the air gap is correct, switch the device on and off briefly, in order to check the direction of rotati on of the rotor. The direction of rotation of the rotor must match up with the direction of the arrow on the housing of the fan. You establish this by a visual check on the admission nozzle at the intake fest or through an excisting hole in the casing.

DANGER! Live wires and connections! Risk of injuries from electric current! Have all electrical work done by a trained electrician only! • If the direction of rotation is wrong, interchange two phases in order to set the correct direction of rotation. • As soon as you have put the fan into operation, check flawless functioning (free movement of the rotor, measurement of the current consumption, check for possible vibrations and noises).

50


NOTE Risk of damage to the fan! If the fan is operated outside the characteristic stated, there is the risk of unstable running and inadmissible vibrations, even possibly its destruction. Do not operate the fan outside the characteristic stated.

• Do not operate the fan outside the characteristic stated. This can happen in the case of a bad flow or excessively high resistance in the system. The fan must run on its prescribed operating point.

• Fill in the attached commissioning record sheet and present it in the event of a warranty claim.

12 Operation

When operating the fan, pay attention to the operating instructions from the motor manufacturer.Regularly check the flawless functioning of the fan (free movement of the rotor, measurement of the current consumption, check for possible vibrations and noises).

12.1 Speed-controlled fan operation

General: Fans can be speed-controlled to reach the required operation point of the installation and user requirements.

Speed-control, maximum speed:The speed specified on the name plate must not be exceeded.

Counter-measures in case of resonance frequencies:Excitation of mechanical components causes resonance frequencies. Improper high oscillations and malfunc-tions could be the result. This may damage impellers, shafts, bearings, housing parts or external components.

Excitation frequencies are caused by e.g. impeller, blade or motor rotations, blade rotational frequencies or aerodynamically. If the excitation frequency nears or meets the resonance frequency of a component, reso-nance oscillation may result in malfunctions. The exciter forces are affected by true running characteristics, balancing situation, aerodynamic forces and damping characteristics of the components.

WARNING! Risks due to resonance frequencies!Avoid continuous fan operation at speeds with increased oscillation values. These speeds must be skipped or deactivated during operation. Make sure that these stages will be passed quickly during start-up to avo-id transient oscillation and exceeding of the admissing oscillation of the resonance frequency. A permanent oscillation monitoring is recommended to ensure a safe and continuous fan operation.

Take a close look on oscillation damages during fan inspection and maintenance. It is recommended to change or increase the maintenance cycle to apply the operating conditions during normal operation speed. In these cases, it is usual to start with short maintenance rates after commissioning. If no damages occur, the rates can be changed stepwise to meet the specified maintenance rates from the operating instructions. This decision has to be made by the installation owner.

Commissioning of speed-controlled fansIt is necessary to check out the fan for oscillations at all normal operation speeds during commissioning. Oscillations on housing and bearing areas have to be determined and evaluated in accordance with DIN ISO 14694 depending on motor power and positioning. The admissible oscillation velocities can be requested from Systemair.

Measurable oscillation velocities depend e.g. on following factors: • positioning• bottom section/foundation state• flow conditions

51AX - 01.2013


The operation point of the fan as well as used external devices and accessories also influence the running characteristics. Thus, an evaluation is only possible when the machine is installed for the proper operation. This evaluation must be done by trained personnel!

Speed-control, special regulations• Changing of the speed causes additional loads on the fan components. • Speed changing during normal regulation must not exceed the admissible motor temperature and the

bearing load. • Spin-up time should be at least 60 seconds. • The service life of fans can be extended by quick passing of the resonance frequencies. • Speed changings should be at max. 16,7 U/sec (1,75 rad/sec) (exception: passing of the resonance fre-

quencies). • The operating instructions of the control device manufacturer must be observed. • Comply with EMC Directive 2004/108/EG (1st March 2005).

General information:• The fan and the frequency inverter should be installed as near as possible to one another. • Use shielded and coated cables. • All components (fan, frequency inverter and motor) should be earthed. • The use of all-pole sinusoidal filters is recommended.• For control with frequency converter a falling below 10 Hz is inadvisable. Exceptions must be agreed

directly with the manufacturing plant.

52


13 Maintenance and upkeep

DANGER! Live wires and connections! Risk of injuries from electric current! Have all electrical work done by a trained electrician only! Periodically check the following according to official requirements, however at least once a year (the fist four points only with the fan switched off!):

• screw connections, specifically the rotor fitting • is there dirt in the fan wheel? If so, remove it. • have accumulations formed on the rotor? If so, remove them. • function of the safety components • function of the control elements • coil resistance • operating current • vibrations which may occur • noises which may occur in the bearings of the electric motor • Motors with extended nipples needs to be re-greased (grease type please take from motor name tag or IMO from the motor manufacture) according to manufacturers‘ instructions.

Check the function of the system and controls (all poles) according to the system maintenance book at least every 3 months, if not required more often.Make the checks of the first four points with the fan switched off. The parameters of the other points may not deviate from the initial figures measured in installation. If one of the parameters deviates from the initial figures, replace the motor or the fan wheel or have them repaired by the manufacturer.In the event of unauthorised interventions, warranty becomes ineffective.Maintain the electric motor according to the enclosed instructions from the manufacturer.Use the enclosed maintenance record.

NOTE Risk of damage to the fan by cleaning with high pressure devices. Only clean the fan manually, with a vacuum cleaner or with compressed air!

NOTE Risk of damage to the fan! Systemair assumes no liability for damage caused by using outside parts. Only use original Systemair spare parts.

14 Fault table, remedying faults

DANGER! Live wires and connections! Risk of injuries from electric current! Have all electrical work done by a trained electrician only!

DANGER! Risk of injuries to the eyes by residue or dust being swirled out when checking the direction of rotation. When checking the direction of rotation of the rotor, wear protective goggles!

If in doubt, get in touch with the manufacturer‘s after-sales service.

Fault Remedy

Fan does not start Check energy supply and motor protection. If in order, check motor. In motors with separated coils, check both speeds.

Volume flow too lowCheck direction of rotation. If necessary, change direction of rotation of motor by interchanging two phases. Check whether the intake area is blocked. Check working point and version of the system.

Motor protection is triggeredCompare the motor data. If in order, check energy supply and motor (short circuit, bearing damage, rotor blocked or grinding), contact after-sales service.

Abnormal noises occur

As a matter of principle: noise development in a fan greatly depends on the installation situation and the operating conditions. For this reason, no generally valid noise data can be given, they always relate to the measu-red conditions. They can be seen from our data sheets.Possible source of fault:• bearing damage on the motor, rotor blocked or grinding• rotor imbalanced or damaged• rotor with differing blade settings• rotor runs in the breakdown area• loose components.Have the motor or possibly the entire fan repaired.

Vibrations

Check working point and version of the system. If the actual total resis-tance of the system is higher than planned, this may result in the fan working in the breakdown area for some types.Contact the manufacturer‘s after-sales service.Damage or dust accumulations on the rotor.Check welding seams on the housing.

15 Stoppage, disposal

DANGER! Live wires and connections!Risk of injuries from electric current!Have all electrical work done by a trained electrician only!

DANGER! Risk of injury if the fan falls down.During dismantling, secure the assembly area against unauthorised access!Use suitable lifting equipment and fitting devices. Do not stand underneath the load.

• To take the fan out of operation, disconnect the electrical connections from the mains.• Take the motor out of operation according to the operating instructions from the manufacturer and

dispose of it as stated there.• After the fan has finally been stopped, dispose of all the materials according to valid directives and

laws!
